the most prominent story arc out of all the characters; the first half of Nichijou involves her desire to become a student in high school, while the second half deals with her fear of being exposed as a robot while at school. Vignettes which are mostly unrelated to the main focus of the series are placed throughout each episode, some of them adapted from Helvetica Standard, another manga by Arawi. Characters Main characters Yūko is an energetic sixteen-year-old high school girl with short brown hair. Yūko's main desire in life is to make every day more fun and interesting than normal, often at other's or her own expense. Because she is often too lazy to do her own homework, she always copies from either Mio or Mai instead. Although she is a generally easygoing person, her mood changes instantly when she is insulted. She often greets people with her catchphrase "selamat pagi" (Malay and Indonesian for "good morning") in a bid to make simple greetings more interesting. Mio is a bright and cheerful girl, who has pastel blue hair pulled into pigtails and held by two small wooden cubes, which are her most identifiable feature. She has a crush on Kōjirō. Though ordinary-looking in comparison to her friends Yūko and Mai, Mio harbors a very short temper, prone to tantrums and acts of violence in order to avoid humiliation; even assaulting a police officer to keep her yaoi manuscript from being discovered. She often has to humor Yūko to make her happy. Being a talented artist, she occasionally draws homoerotic pictures of Kōjirō in her notebooks and, under a male pseudonym, has entered several erotic manga into contests that promise serialization to the winner. Near the end of the manga, Mio finally wins one of the contests she entered, though it is unknown whether or not she actually accepted the publisher's offer due to her paranoia about her art. She is sixteen years old. Accordingly to a daydream of Yūko's, the cubes in her hair are supposedly magical artifacts from a Fey Kingdom zeppelin that fell on her head. Mai is a quiet and intelligent girl who wears glasses. Before the events of the manga series, Mai had lived in Alaska and moved to Japan due to her father's job. Likely as a result of this, Mai is fascinated by Shinto shrines and will always visit whenever she sees one.
